| Notes | Most bioassessment is confined to small, wadable streams. This article discusses the importance of assessing larger streams, and assessment methods focusing on benthic diatom assemblages. Lowland streams are contrasted with mountanous streams, and differences between rivers east and west of the Cascade Mountains are noted. The Umpqua River had more mountainous characteristics, and had similarities to east-side streams. The authors note that, while high nutrient concentrations were found in the mainstem Umpqua River, they were diluted after the North Umpqua River joined the mainstem. |
